Emmen Air Base (ICAO: LSME) is a military airfield operated by the Swiss Air Force, located near the city of Emmen in the canton of Lucerne, central Switzerland. It serves as one of the most important installations for Swiss military aviation, including aircraft maintenance, testing, and operational squadrons. The base is closely associated with the Federal Aircraft Factory (F+W Emmen, later RUAG Aviation), which has historically designed, manufactured, and maintained Swiss military aircraft on-site. It is not a commercial passenger airport and does not serve scheduled civilian airline traffic. Emmen Air Base is occasionally used for airshows and public events, offering the Swiss public a rare glimpse into military aviation operations. Its IATA code EML reflects its registration in aviation databases, though it handles no regular commercial flights.
